The Effect of Upper Blepharoplasty on Vision Quality and Eye Anatomy in the Early Postoperative Period

What this Trial Is About

This research investigates the effects of upper blepharoplasty (UB) surgery on vision quality in people with functional dermatochalasis, a condition where excess skin on the upper eyelid causes visual field obstruction and discomfort. The study focuses on anatomical changes in corneal topography (CT) and functional changes in tear film (TF) and contrast sensitivity (CS) during the early postoperative period, as previous studies mainly explored late effects. Researchers aim to clarify how UB impacts vision by examining these factors in detail, since the exact reasons for improved vision quality after surgery are not well understood. Participants will undergo UB surgery where excess skin folds on the upper eyelids are removed under local anesthesia, without removing underlying muscle. Before surgery, CS, TF analysis, and CT measurements will be taken. Follow-up visits will occur 7 days and one month after surgery, repeating these same tests to monitor changes. The study uses specialized devices for TF and CT analysis at Lens LTD, while CS tests take place at the University Eye Department. Throughout the study, participants will have detailed eye exams and medical histories recorded, with grading of the eyelid appearance. Researchers will monitor contrast sensitivity under bright light, tear film quality, and corneal shape before and after UB. The primary outcome is contrast sensitivity measured before surgery, 7 days, and one month after. Data collected will help understand the anatomical and functional vision changes after UB and contribute to improving treatment approaches.
